- The course examines advanced modeling of the infiltration process of water into the soil, the transformation of effective rainfall in direct runoff and the flood routing directed to hydraulic infrastructures design, to water resources management and to floodscontrol.
The main expected learning results will be:
•knowledge and understanding of the hydrological cycle and key hydrological processes, rigorous or simplified approaches in estimating infiltration rates and soil moisture evolution, lumped or semi-distributed models that describe rainfall-runoff transformation and synthesize storm hydrographs, hydraulic and hydrological methods to route flood waves through river systems, real-time flood forecasting system;
•skill to select and apply proper advanced modeling in order to represent the main components of the hydrological cycle as infiltration process and runoff generation and to simulate flood routing. - 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 of functions of single and several variables, partial differential equations.

- HYDROLOGY II
The exam of the course consists of a written test and an oral discussions over the contents of the course, 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 oral exam, lasting about 45 minutes, is directed to check out the knowledge level over the course contents, the acquired ability to apply the studied models and techniques and the ability to select the proper methodology by self-judgement. Furthermore, the oral exam has also the objective to evaluate communication skills and the usage of an appropriate language about the theoretical and practical subjects of the course.
The grade of the exam is certified with the local grade system, which is a number on a scale from 18 to 30. The exam mark will be provided by a weighted average of the results obtained in the separate tests, with the following weights: written test: 1/3; oral test: 2/3.

- The course deals with advanced models describing the infiltration process of water into the soil, the transformation of effective rainfall in direct runoff and the routing of a hydrograph from an upstream to a downstream river section. The program involves also the description of the real-time flood forecasting system. All these elements are directed to the design of hydraulic infrastructures, to the control of floods and to the management of water resources. The course is organized in different units as follows:
•Rainfall infiltration process: i) Numerical solution of the Richards equation.; ii) Conceptual semi-analytical models for conditions of immediate ponding and their extension for real rainfall patterns (models of Philip and Green-Ampt).
•Effective rainfall-direct runoff transformation: i) Geomorphological instantaneous unit hydrograph; ii) Semi-distributed approach (Clark model).
•Flood routing: i) The Saint Venant model; ii) Kinematic and diffusive models; iii) The Muskingum method.
•Real-time flood forecasting system.
