Review Types of Problems

ADDRESSING LWTB ADDRESSING L TB PROBLEM AREAS PROBLEM AREAS • Understanding the Cause of the Problem • Not all Flooding is the same • What Flooding definition is going to be used? • Water Quantity vs. Water Quality • Role of Public Education • Characterization and Contrast • Type or reason(s) for flooding may effect liability • Magnitude of flooding may cause liability • Ability for Public Access and/or Maintenance

LWTB PROBLEM TB PROBLEM TYPES PES Ty Typical Ta Tailwater Flo Flow Condi Conditi tions ons Note: Equilibrium is eventually reached (drainage outward) to rid the potential energy.

LWTB PROBLEM TB PROBLEM TYPES PES “T “Tailwater Backup” Note: – When tailwater is far higher than expected (like an unusual tide event or surge event), it may backup the headwater and cause flooding even during a normally routine storm event since there is nowhere for water to go.

LWTB PROBLEM TB PROBLEM TYPES PES In Inad adeq equate Collection Collection This happens when there is no means to collect the water to get in to the pipes and/or to the downstream collection.

LWTB PROBLEM TB PROBLEM TYPES PES Po Poor Con Convey eyance ance This happens when pipes or inlets are too small to keep up with water or are plugged
