The Technical Assistance Program for Watersheds (TAPwaters) is dedicated to the use of geographic information system (GIS) and hydrological modeling technology for the advancement of watershed research and management.
The TAPwaters office is located in the Spring Creek annex and houses two high-end workstations, a 4x5-ft.
This approach can also be used in a number of other ways to investigate the distribution of radioisotopes in the environment through measurements of a wide range of environmental and ecological samples.
UK Environmental Change Research Centre, University College London ( Before sending samples for analysis it is important to contact either Handong Yang or Neil Rose (see Contacts) regarding up-to-date costs and the time from receipt of samples to reporting as this can vary depending on demand.
