About Conceptual Diagrams

This page gives background information on what conceptual diagrams are and how they are used in CADDIS.

This page explains changes in basal energy sources with urbanization, with an overview of terrestrial leaf litter dynamics in urban streams and how urbanization can affect primary production, respiration, and dissolved organic carbon quality.

Urbanization - Water and Sediment Quality

This page shows water and sediment quality issues associated with urbanization, it gives an overview of conductivity as an indicator and shows how this affects nitrogen loading, and their effects on stream biota.

Urbanization - Stormwater Runoff

This page introduces you to impervious surfaces associated with urbanization,and includes background information on how impervious surfaces affect biotic condition and threshold values of impervious surfaces.

Urbanization - Riparian/Channel Alteration

Introduction to riparian and channel alteration associated with urbanization, summary of how riparian urbanization affects channel morphology, summary of how urbanization affects riparian hydrology, overview of stream burial associated with urbanization.
