متن کاملCalifornia’s Sacramento San Joaquin Delta Conflict: from Cooperation to Chicken
California’s Sacramento-San Joaquin Delta is the major hub of California’s water supply system and is central to the ecosystem of many native threatened and endangered species. Conflicts over the Delta have evolved over more than a century. This paper traces changes in this conflict in game theoretic terms, with its implications for the region’s physical and ecological decline and governance...
متن کاملNitrate in tile drainage of the semiarid Palouse Basin.
Topographically heterogeneous agricultural landscapes can complicate and accelerate agrochemical contamination of streams due to rapid transport of water and chemicals to poorly drained lower-landscape positions and shallow ground water. In the semiarid Palouse region, large parts of these landscapes have been tile drained to enhance crop yield. From 2000-2004 we monitored the discharge of a ti...
متن کاملPhosphorus losses through agricultural tile drainage in Nova Scotia, Canada.
Tile drainage water from agricultural fields commonly exceeds environmental guidelines for phosphorus (P) in rivers and streams. The loss of P through artificial drainage is spatially and temporally variable, and is related to local factors. This study characterizes variability in total P (TP) and soluble reactive P (SRP) concentrations in weekly drainage samples from 39 agricultural fields in ...
متن کاملEvaluation of Soils for Suitability for Tile Drainage Performance
Tom Scherer Extension Agricultural Engineer The presence of salts and high water tables in North Dakota soils due to an extended climactic wet cycle recently has stimulated interest in the installation of tile drainage systems. The tile controls the water table and encourages the leaching and removal of salts from the soil above the tile lines. This improves soil productivity, culminating in im...
