Controlling Stormwater Runoff That Limits Water Availability and Dryland Crop Productivity

Approaching the photosynthetic limits of crop productivity.

Impact of Runoff Water Quality on Future Nursery Crop

changes in the 1980s. Droughts and water regulations required increased use of lowvolume irrigation, severe freezes promoted the use of fabric covers for cold protection, and governmental immigration reform necessitated re-evaluation of personnel resources. Production practices were required that used smaller quantities of fertilizer and pesticides. Additional restrictions limited the disposal ...

Effects of Stormwater Runoff from New Development

Most people know that urban runoff is a problem. Few understand just how harmful it can be for rivers and streams. To secure better watershed planning urban runoff control, we must first convince the public and its officials that they are needed. We need to show clearly and convincingly both the nature and the magnitude of the water quality and quantity problems that poorly planned and managed ...

Runoff Characteristics of Stormwater and Washoff Water Quality from Roof and Road Surfaces

Owing to overflows from combined sewer pipe systems, water quality of receiving waters, including urban rivers, has become worse year by year. Appropriate countermeasures that can mitigate the overflows, therefore, must be developed promptly. The authors have investigated a distributed simulation model of water quality and stormwater runoff in urban sewer pipe systems. First, a surface routing ...

Comparison of Contaminant Transport in Agricultural Drainage Water and Urban Stormwater Runoff

Transport of nitrogen and phosphorus from agricultural and urban landscapes to surface water bodies can cause adverse environmental impacts. The main objective of this long-term study was to quantify and compare contaminant transport in agricultural drainage water and urban stormwater runoff. We measured flow rate and contaminant concentration in stormwater runoff from Willmar, Minnesota, USA, ...
