Slide 2

Detention Pond Classification Watershed Protection and Development Review (WPDR) Texas Commission of Environmental Quality (TCEQ) Project to characterize detainment lakes

Slide 3

Building a Database Existing point include class information base Electronic variants of maps Berm statures by means of memory (maintenance group) Retrieval of whatever other existing maps Result: Nearly exhaust information base

Slide 4

Course of Action So what do you do? Convey the assistant!

Slide 5

Mission Berm or Dam? Berm/Dam measurements Take picture inside the lake Take picture downstream Description of what falsehoods 100 yds downstream

Slide 6

Engineer\'s Request Use of GIS to: Find contributing waste zone into a lake Estimate volume of lake Estimate berm/dam stature Delineate immersion range Determine what exists around there

Slide 15

Contributing Drainage Area Find waste zone at lake delta. Dissect Map : Flow collection = 2701 x (10 x 10) m 2 x (1 km/1000m) 2 = 0.2701 km 2

Slide 16

Volume of Pond Create new polygon include class Analyze outline

Slide 17

Volume of Pond Export Table to .dbf record Analyze delineate

Slide 18

Volume of Pond Open in Excel and Run Macro Analyze delineate

Slide 19

Inundation Area Delineate immersion zone Analyze outline

Slide 20

Results Use of GIS to: Find contributing waste zone into a lake Estimate volume of lake Estimate berm/dam tallness Delineate immersion zone Determine what exists around there

Slide 21

Additional Work Use another apparatus TIN Volume instrument for computing lake volume Finish system for assessing immersion territory Automate a greater amount of the examination Visual Basic Model Builder UML
