Educational objectives The course examines the main hydrological processes as the rainfall formation, the effective rainfall and the direct runoff generation, and provides means to measure and estimate the quantities of most interest in the design of hydraulic infrastructures.

The main expected learning results will be:
•knowledge and understanding of hydrological cycle and key hydrological processes, measurement techniques of the main involved variables, basic methods for estimating effective rainfall (SCS-CN method) and direct hydrograph (lumped and semi-distributed approaches), direct and indirect stochastic methods to estimate design discharge;
•skill to select and apply measure techniques of the main hydrological quantities, proper basic modeling in order to represent the main components of the hydrological cycle as infiltration process and runoff generation, appropriate approach in estimating flood frequency and design variables;
skill to select and design water distribution systems and sewer systems.
Prerequisites In order to deeply understand mathematical models involved in the program of the course and to reach the expected learning results the following elements are required:
•Mathematical analysis: analytic functions, differential and integral calculus.
•Physics and Rational Mechanics: vector calculus, cardinal equations of statics and dynamics.
•Hydraulics: elements of Hydrostatics, pressurized flow.
Teaching methods Classroom lectures on all subjects of the program with interactive involvement of students. Classroom exercises performed on the blackboard. Seminar frontal lessons with projector support.

Learning verification modality The exam of the course Hydrology and Municipal Water Systems consists of a written test and two oral discussions over the two parts of the course program (Hydrology I and Municipal Water Systems), to be performed separately or in the same exam session.
The written exam, lasting 1 hour, consists of the solution of two problems related to the hydrological modeling, the first one of computational type and the second one of both computational and conceptual kind. The test has the aim to prove the ability of understanding the proposed problems and applying theoretical knowledge in order to obtain quantitative results, the skill to elaborate by self-judgment proper remarks, and the capacity to effectively communicate in a written form.
The two oral exams, each one lasting about 30 minutes, are directed to check out: i) the knowledge level over the course contents (divided in into the two parts of Hydrology I and Municipal Water Systems), ii) the acquired ability to apply the studied models and techniques, iii) the ability to select the proper methodology by self-judgement, and iv) the communication skills and the usage of an appropriate language about the theoretical and practical subjects of the course.
The final evaluation will be provided by a weighted average of the results obtained in the separate tests, with the following weights: written test: 1/6; oral test related to the first part of the course program (Hydrology I): 1/3; oral test related to the second part of the course program (Municipal Water Systems): 1/2.
Extended program The course deals with the basic hydrological processes as the rainfall formation, the effective rainfall and the direct runoff generation, and describes measurement techniques of the main hydrological variables and methods for estimating hydrological variables in order to design hydraulic infrastructures. The course is organized in different units as follows
•Statistical hydrology
•Formation of precipitation: i) Space-time characteristics of rainfalls; ii) Rainfall measurements and design of raingauge networks; iii) Rainfall Intensity-Duration-Frequency curves.
•Rainfall infiltration: i) Formulation of the theoretical problem; ii) Estimate by the SCS-CN method.
•Rainfall-runoff transformation: i) Hydrograph formation and separation; ii) Effective rainfall-direct runoff transformation by the unit hydrograph methodology with a single or a series of reservoirs; iii) Semi-distributed approach: the time-area method.
•Stream flow: i) Measurements of discharge; ii) determination of the stage-discharge curve.
•Determination of the design discharge: i) Direct and ii) Indirect approaches.
Water distribution systems: urban demand of water; water supply sources; calibration and test of water distribution systems and hydraulic networks; pipes characteristics; valves, tees, bends and reducers; tanks, siphons; pumps and pumping stations, transient control (air chamber); technical norms of water distribution systems. Sewer systems: hydraulic design of storm sewers and of wastewater sewers; side-overflow weirs, pumping stations.
