“…We hypothesize that though undeveloped catchments had greater terrestrial biomass, they lacked the runoff velocities required to transport biomass to the pond (Corbett and others 1997a). The higher runoff velocities from more developed catchments were more capable of transporting organic matter into ponds either as sheet flow over lawns or as channeled through storm drains (Jacobson 2011). Here, it is important to note that impervious surface coverage never exceeded about 50%.…”

“…Stormwater ponds, as settling basins, are very efficient particle traps (Verstraeten and Poesen 2000), so it is likely that pond sediment accumulation rates are controlled by suspended particulate input flux. As mentioned previously, impervious surfaces are known to increase the volume of runoff waters and the load of suspended particulate matter (Corbett and others 1997a;Grimm and others 2008;O'Driscoll and others 2010;Jacobson 2011;Nagy and others 2011;Walsh and others 2012;Fletcher and others 2013). The final result being ponds with greatest impervious surfaces have the greatest runoff fluxes bearing the greatest particulate loads, which lead to the greatest sediment accumulation rates.…”

“…With respect to N, mean stormwater pond sediments were approximately double the values reported for both natural lakes and reservoirs (Table 6) This study found that rates of C, N, and P burial were directly correlated with %Ip (versus individual concentrations) which demonstrates that the bulk sedimentation drives nutrient burial rates (Table 3). Though %Ip is correlated with a myriad of anthropogenic impacts, it directly influences the region's hydrology by greatly increasing the quantity and velocity of runoff water, which subsequently increases the load of suspended particulate matter (Corbett and others 1997a;Walsh and others 2005;Grimm and others 2008;Jacobson 2011;Nagy and others 2011;Fletcher and others 2013). This high load of suspended particulate matter, allowed to settle in the stormwater pond's basin, can ultimately lead to increased bulk mass accumulation and subsequent burial of particleassociated C and nutrients.…”

“…One of the most striking of these landscape changes is the rise in impervious surfaces, which is often associated with a variety of impacts to downstream receiving waters (Holland and others 2004). Impervious surfaces, such as roads, parking lots, and buildings, restructure urban hydrology by increasing the volume and velocity of runoff water during storm events, which can amplify flood risk, erosion, and pollutant transport (Corbett and others 1997a;Grimm and others 2008;Jacobson 2011). Furthermore, impervious surfaces displace vegetated surfaces capable of fixing carbon (C) and storing nutrient pollutants in biomass and soils.…”

Drivers of Sediment Accumulation and Nutrient Burial in Coastal Stormwater Detention Ponds, South Carolina, USA

et al. 2018

Stormwater detention ponds are widely utilized as control structures to manage runoff during storm events. These ponds also represent biogeochemical hotspots, where carbon (C) and nutrients can be processed and buried in sediments. This study quantified C and nutrient [nitrogen (N) and phosphorus (P)] sources and burial rates in 14 stormwater detention ponds representative of typical residential development in coastal South Carolina. Bulk sediment accumulation was directly correlated with catchment impervious surface coverage (R 2 = 0.90) with sediment accumulation rates ranging from 0.06 to 0.50 cm y -1 . These rates of sediment accumulation and consequent pond volume loss were lower than anticipated based on maintenance guidelines provided by the State. Nalkanes were used as biomarkers of sediment source; the derived terrestrial aquatic ratio (TAR HC ) index was strongly correlated with sediment accumulation rate (R 2 = 0.71) which, in conjunction with high C/N ratios (16-33), suggests that terrestrial biomass drives this sediment accumulation, with relatively minimal contributions from algal derived material. This is counter to expectations that were based on the high algal productivity generally observed in stormwater ponds and previous studies of natural lakes. Sediment C and nutrient concentrations were consistent among ponds, such that differences in burial rates were a simple function of bulk sediment accumulation rate. These burial rates (C: 8.7-161 g m -2 y -1 , N: 0.65-6.4 g m -2 y -1 , P: 0.238-4.13 g m -2 y -1 ) were similar to those observed in natural lake systems, but lower than those observed in reservoirs or impoundments. Though individual ponds were small in area (930-41,000 m 2 ), they are regionally abundant and, when mean burial rates are extrapolated to the regional scale (% 21,000 ponds), ultimately sequester 2.0 9 10 9 g C y -1 , Received 28 July 2017; accepted 11 November 2017; published online 16 January 2018Electronic supplementary material: The online version of this article (https://doi.org/10.1007/s10021-017-0207-z) contains supplementary material, which is available to authorized users.

General commentsOverall I was quite happy with the quality and scope of this paper. It is very well written and contains some important findings. Some general and more specific comments are provided below. I think the authors should have the opportunity to think about a few of my comments below; this calls for minor revision.While the paper concerns both hydrology and water quality, I think more attention is given to the latter. I would have liked to seen more results on hydrology. Maybe you could provide a graph (with associated discussion in the text) showing mean event runoff coefficients for each catchment? Given that the paper is already fairly long, this might not be possible. In any case, I recon you could expand your hydrological findings in a separate journal paper.• Response: We are planning a separate paper that details the hydrologic results of this work. However, since both reviewers requested more hydrologic data, we have added a table in the appendix that provides more details on runoff and storm characteristics (Table A1) In the discussion, you present a conceptual model of urban watershed ecosystem function and describe four periods of change. You suggest that the model is for arid urban catchments. I think it would be worth fleshing this section out a bit more. In doing this, maybe you could firstly describe in a general way, what is natural arid catchment hydrology.• Response: We have limited space to add more discussion here, and we already have some information on arid hydrology in the introduction (lines 191-194), and we reference key literature (Osterkamp and Freidman, 2000. We have however, included a bit more discussion about how this model might differ in other regions (now lines 611-618).Where I'm from, the "third" phase in your diagram is very different. We have been installing distributed stormwater infrastructure for the last 15 years. But, our systems are generally designed for pollutant-load reduction-aimed to protect our largest receiving water (a bay). These systems are not designed to restore/protect natural hydrology. Because of this, runoff/ratios tend to still be c...

[1] Statistical models relating anthropogenic modifications of the watershed landscape to alterations in streamflow are often plagued by heterogeneity in background watershed conditions and coinciding trends in climate that can complicate the interpretation of clear statistical relationships. This study introduces the use of panel regression as a modeling approach that can better accommodate basin heterogeneity and identify more robust signals between anthropogenic impacts on the watershed landscape and hydrologic response. Panel regression techniques pool multidimensional data recorded across individuals (i.e., watersheds) and through time to better characterize within-and between-variability in the hydrologic data set. The separate attribution of variability to both time and space dimensions enables the method to better identify response characteristics that are generalizable across watersheds. This study introduces in detail two broad classes of panel regression models (the fixed effects and random effects models) that may be particularly useful in the context of identifying and quantifying the impact of human-induced landscape alterations on hydrologic response. The technique is presented in a case study relating watershed urbanization to changes in the annual runoff coefficient for 19 watersheds in the Northeast United States. Comparisons are made against more standard cross-sectional and time-based regression analyses. The results show that the estimated relationship between urbanization and the annual runoff coefficient in this region is highly dependent on the dimensions of data examined (space or time) and model structure selected, with the most sophisticated and appropriate model suggesting that no significant relationship can be detected.
