Runoff also includes groundwater that is discharged into a stream; streamflow that is composed entirely of groundwater is termed base flow, or fair-weather runoff, and it occurs where a stream channel intersects the water table.
Thankfully, improved sewage treatment processes and efforts to divert dry-weather runoff to our treatment plants, rather than allowing it to dribble onto or under our beaches, have allowed the water in Santa Monica Bay to improve.
It would build the infrastructure to capture both the daily dry-weather runoff (from lawn sprinklers, for example) and the winter rainwater that gushes down the pavement and into storm drains.
During dry weather the runoff is first channeled into sewage treatment plants.
The model includes the following components: weather, surface runoff, return flow, percolation, ET, transmission losses, pond & reservoir storage, crop growth & irrigation, groundwater flow, reach routing, nutrient & pesticide loading, water transfer.
Daily available soil moisture was computed as the net of current available water above the wilting point plus rainfall minus evapo-transpiration as a function of leaf area index and current weather, and runoff above the soil carrying capacity.
Older mountain ranges, eroded by weathering and runoff, mark zones of earlier plate-margin activity.
The results show that although a large amount of Si is cycled by plants, weathering and runoff contribute similarly to, or even more significantly than, plant cycling.
Main source of greater EC values in current study can be linked to the geology of catchment area of the Kurang, soil weathering, surface runoff and dumping of untreated sewage.
Unless results are certified within four to six weeks, it will be too late to carry out another election before harsh weather makes a runoff impossible, officials say.
