“…They differ in ease of adoption, effectiveness, cost of implementation, and offer a range of options for a variety of situations. These practices and related factors have been discussed in several previous publications (Carter, 1990;Carter et al, 1993;Sojka and Carter, 1994;Sojka, 1998). The evolution of practices has reflected both changes in the motivation for conservation and improvements in available conservation technologies.…”

“…Previously dominant methods of irrigation, particularly furrow, were known to produce large amounts sediment from off field transport and irrigation canal erosion (e.g. Tanji et al, 1980;Carter et al, 1993;Koluvek et al, 1993). Drip irrigation has been shown to result in much lower off-field transport of sediment than sprinkler and furrow methods (McHugh et al, 2008), and was introduced to California in the early 1960s.…”

“…This phenomenon has generally been followed by a rapid decrease in sediment flux during the 20 th century, primarily from river impoundment, and to a lesser degree changes in agricultural practices and afforestation (Vorosmarty et al, 2003;Walling, 2006). Changes in agricultural practices over the last century have in many cases led to decreases in off-field sediment transport with the implementation of soil conservation practices, including changes to less erosive irrigation techniques (Carter et al, 1993;Koluvek et al, 1993;Tomer et al, 2010;Wilson et al, 2014).

This study is an investigation into the roles of wildfire and changing agricultural practices in controlling the inter-decadal scale trends of suspended sediment production from semi-arid mountainous rivers. In the test case, a decreasing trend in suspended sediment concentrations was found in the lower Salinas River, California between 1967 and 2011. Event to decadal scale patterns in sediment production in the Salinas River have been found to be largely controlled by antecedent hydrologic conditions. Decreasing suspended sediment concentrations over the last 15 years of the record departed from those expected from climatic/hydrologic forcing. Sediment production from the mountainous headwaters of the central California Coast Ranges is known to be dominated by the interaction of wildfire and large rainfall/runoff events, including the Arroyo Seco, a ~700 km 2 subbasin of the Salinas River. However, the decreasing trend in Salinas River suspended sediment concentrations run contrary to increases in the watershed's effective burn area over time. The sediment source area of the Salinas River is an order of magnitude larger than that of the Arroyo Seco, and includes a more complicated mosaic of land cover and land use. The departure from hydrologic forcings on suspended sediment concentration patterns was found to coincide with a rapid conversion of irrigation practices from sprinkler and furrow to subsurface drip irrigation. Changes in agricultural operations appear to have decreased sediment supply to the Salinas River over the late 20 th to early 21 st centuries, obscuring the influence of wildfire on suspended sediment production.

Of the 15,000,000 ha (37,000,000 acres) of irrigated land in the U.S., 21% is affected by soil erosion to some extent. Irrigation-induced soil erosion has been studied, primarily in the Northwestern United States, since 1940. A number of studies have measured annual sediment yields from furrow-irrigated fields exceeding 20 t/ha (9 tons/acre) with some fields exceeding 100 t/ha (45 tons/acre). Under the center-pivot sprinkler method, sediment yields as high as 33 t/ha (15 tons/acre) have been measured. Annual sediment yields as high as 4.5 t/ha (2 tons/ acre) were measured from irrigation tracts. Erosion is seldom excessive on slopes less than 1% and is often excessive on slopes greater than 2%. Erosion reduces the agricultural productivity of the fields and causes off-farm damages. In southern Idaho, crop yield potential has been reduced by 25% due to 80 years of irrigationinduced erosion. Some irrigation districts spend more than $50,000 annually to remove sediment from drains. Sediment in irrigation return flows causes major water-quality degredation problems in several rivers in the Western United States.
