introduction
Introduction

Problem?.

  • Constructed wetland : a solution for nitrate removal
  • Design of wetland- location identification
  • Evaluation of effectiveness of constructed wetland

Depth of water?

Residence time?

Objectives

  • To determine monthly average depth of water in wetland
  • To find out the area extend of wetland (monthly)
  • Estimate residence time
study area
Study area
  • Middle Wabash- Little Vermillion
  • HUC 05120108
data required
Data Required
  • Data required for location identification
  • Data required to find out the depth
  • Ditch flow to the wetland
  • Wetland Characteristics- size, normal pool depth
  • Watershed Characteristics- area, percentage tile drained
  • Evapotranspiration from wetland
methodology
Methodology
  • Begin with available ditch flow data and dam characteristics
  • Model the wetland inflow and outflow (possibly HEC)
  • Obtain monthly depth of water in wetland
  • Try to estimate the ditch flow data- as a function of watershed characteristics, rainfall etc.
