The objective of the hydrology program is to prepare a model which will provide predictions of the hydrologicMate of a coniferous watershed at any desired time and in any desired place, where state is defined by the inputweds of the other submodels or systems, particularly the producer and biogeochemical processes. Subsurface flows the dominant runoff mechanism in coniferous watersheds and one of the least understood processes inrydrology. Research projects in hydrology seek to understand this process using three different techniques. Onewoject relates subsurface flow to soil properties using direct measurement techniques. Another project approacheshe problem using simulation techniques. The third project utilizes systems analysis and statistical decomposition#f runoff events to make inferences about subsurface flow. These studies of hydrologic processes will bencorporated into a hydrologic model and linked to studies of other systems. The first step in linking our model9ith those of other groups is watershed stratification, a problem now solved by our modeling efforts.
