Modeling hydrology and in-stream transport on drained forested lands in coastal Carolinas, U.S.A.

Abstract

This study summarizes the successional development and testing of forest hydrologic models based on DRAINMOD that predicts the hydrology of low-gradient poorly drained watersheds as affected by land management and climatic variation. The field scale (DRAINLOB) and watershed-scale in-stream routing (DRAINWAT) models were successfully tested with water table and outflow data from a 25 ha, 340 ha, 2950 ha forested watersheds and an 8 140 ha mixed land use watershed in North Carolina (NC), USA. Results of linking DRAINWAT with a simple in-stream nitrogen transport model with a first order decay rate indicated its potential use as a tool for estimating N losses from the poorly drained coastal watersheds.
