“…These sediment fluxes can be modulated when crossing ditch margins. If gullies are connecting the adjacent field and the ditch, the sediment loads in the overland flow can reach very high concentrations (Lecce et al 2006;Tucker and Bras 1998). However, if ditches are connected to the adjacent fields by intact grass strips, the sediment loads may be consistently attenuated before reaching the ditch (Gumiere et al 2011;Huang et al 2002;Tucker and Bras 1998).…”

“…However, if ditches are connected to the adjacent fields by intact grass strips, the sediment loads may be consistently attenuated before reaching the ditch (Gumiere et al 2011;Huang et al 2002;Tucker and Bras 1998). Sidewall erosion is deemed to be a minor source of suspended sediments that are transported throughout vegetated ditches (Lecce et al 2006). However, it has been punctually observed for substantial flood events occurring after maintenance operations (Levavasseur et al 2014).…”

“…In the latter catchment, the sedimentation conditions are favored by gentle slopes ranging from 1 to 4 ‰ ( Lecce et al 2006). Moreover, Flora and Kröger (2014) measured the total suspended solid removal in vegetated ditches that were equipped or not by consecutive weirs, ranging from 72 to 94 %.…”

“…The increased water conveyance potential facilitates the rapid removal of excess water on cropped plots and limits the potential overflow of ditches, positively affecting waterlogging and erosion control (Levavasseur 2012). The increased water conveyance potential combined with a smaller hydraulic retention time may lead to decreased infiltration processes (Fiener and Auerswald 2003;Kröger et al 2009;Lecce et al 2006) and, in turn, to reduced groundwater recharge and increased downstream water flow. The latter impact on groundwater recharge, however, may vary according to the type of clearing technique.…”

Agriculture must now feed the planet with the lowest environmental impact. Landscape management is a means to protect natural resources from the adverse impacts. In particular, the adequate management of ditches could improve crop quality. Here, we review ditch design and maintenance. We found the following major points: (1) ditch networks have been primarily designed for waterlogging control and erosion prevention. Nonetheless, when properly managed, farm ditches provide other important ecosystem services, namely groundwater recharge, flood attenuation, water purification, or biodiversity conservation. (2) All ditch ecosystem services depend on many geochemical, geophysical, and biological processes, whose occurrence and intensity vary largely with ditch characteristics. (3) The major ruling characteristics are vegetative cover; ditch morphology; slope orientation; reach connections such as piped sections and weirs, soil, sediment and litter properties, biota, and biofilms; and network topology. (4) Ditch maintenance is an efficient engineering tool to optimize ecosystem services because several ditch characteristics change widely with ditch maintenance. For instance, maintenance operations, dredging, chemical weeding, and burning improve waterlogging and soil erosion control, but they are negative for biodiversity conservation. Mowing has low adverse effects on biodiversity conservation and water purification when mowing is performed at an adequate season. The effects of burning have been poorly investigated.

The contributions of drainage ditches to the accelerated eutrophication of rivers have rarely been assessed, especially for the Three Gorges Reservoir (TGR) drainage ditches. Forty drainage ditches in the TGR from multiple land use types were extensively investigated for 10 parameters of water quality. The results showed that the concentrations of total nitrogen (TN) and total phosphorus (TP) in the TGR drainage ditches were generally far higher than the internationally recognized eutrophication threshold. Based on this study, both ditch water and sediments from residential land and roadside land had the highest concentrations of nutrients. Possible sources of these nutrients include sewage water and septic tank overflow. Forestland had significantly lower concentrations of nutrients. Residential ditches had higher values of electrical conductivity (EC) and total dissolved solid (TDS) values and lower dissolved oxygen (DO) concentrations. Forestland had lower values of EC and TDS values and higher DO concentrations. The results indicate that the nutrients that have accumulated in the sediments have significant impacts on the water quality in adjacent ditches. A long‐term plan must be developed to more strictly control the external loading of nutrients from surrounding land. Action plans to promote the growth of wetland plants in drainage ditches are important for increasing agrochemical retention in the TGR drainage ditches. TGR drainage ditches from residential zones must be actively managed by cleaning and sediment removal to control the risk of nutrients being released into the reservoir.
