WATER SYSTEMS UNDERGO A VARIETY OF NATURAL AND HUMAN INDUCED DISTURBANCES THAT IMPACT QUANTITY AND QUALITY OF WATER. THESE WATER SYSTEMS ARE IMPORTANT FOR THE SUSTAINABILITY OF AGRICULTURAL SYSTEMS, URBAN NETWORKS, AND ECOSYSTEM SERVICES. IN THESE CHANGING CONTEXTS, IT IS IMPORTANT TO BETTER UNDERSTAND THE EXPECTED IMPACT OF PLANNED CONSERVATION OR GREEN INFRASTRUCTURE STRATEGIES ON SECURING SURFACE AND GROUNDWATER SUPPLIES BY CONSIDERING DOMINANT FLOW PATHS AND URBAN-ECOLOGICAL ZONES OF INFLUENCE. FURTHERMORE, IDENTIFICATION OF SUCH ECOSYSTEM LOCATIONS THAT DEGRADE THESE FLOWS SPATIALLY AND TEMPORALLY WILL BE KEY TO PROVIDING THE INSIGHTS FOR SUSTAINING URBAN-ECOLOGICAL RESILIENCE OF WATERSHEDS THAT AFFECT THE LARGER SNAKE AND COLUMBIAN RIVER BASINS. HENCE, THE OBJECTIVES FOR UNDERSTANDING THE CHANGING NATURE OF THE QUANTITY AND QUALITY OF WATER IN URBANECOLOGICAL SYSTEMS IN THE INLAND PNW WILL REVOLVE AROUND (I) WATER SIGNATURES AND (II) URBAN STORMWATER. THE PROJECT AIMS TO (I) STUDY THE VARIATION OF THE WATER SIGNATURES OF PRECIPITATION AND SURFACE WATERS SAMPLED ALONG THE FOUR TRIBUTARIES OF THE SOUTH FORK PALOUSE RIVER, (MISSOURI FLAT CREEK, PARADISE CREEK, SUNSHINE CREEK, DRY FLAT CREEK) TO REVEAL PATTERNS OF CONNECTEDNESS AND (II) INVESTIGATE THE POTENTIAL OF CURRENT AND FUTURE COMPACTED LANDS IN URBAN AND AGRICULTURAL AREAS TO INCREASE WATER LOSSES AND POLLUTION TO AQUATIC SYSTEMS. THESE OBJECTIVES WILL HELP DEVELOP CONSERVATION STRATEGIES AS A WARMING CLIMATE REDUCES RELIABLE LONG-TERM SNOWMELT AND SUMMER FLOWS. THE DIRECT IMPACTS TO THE WATERS SYSTEMS ARE UNKNOWN AND THIS PROJECT INTENDS TO PROVIDE ASSESSMENTS OF RELIABILITY, RESILIENCE, AND FAILURES TO CONSIDER ADAPTATION AND SUSTAINABLE FOOD AND AGRICULTURE PRACTICES IN THE INLAND PNW AND SIMILAR STRESSED AREAS.
