1st Section: Inland navigation. Questions. 1. Infiltration of water under the foundations and round retaining works and through the lengthwise embankments of navigable waterways. Under-pressures. Means of preventing or reducing infiltrations and opposing their destrictive action.--2. Regularisation and canalisation works of rivers and streams. Results obtained, more especially as regards the new greadients and the alterations in the vertical and horizontal configuration of the bottom, and also the movements of solid matters swept along.--3. Progress made in recent years in the dispositions and exploitation of navigation works on canals and canalised rivers, and also in the arrangement of their access.

Communications: 1. Canals serving both the needs of navigation and agriculture. Reciprocal utilisation of navigation canals for irrigation and irrigation water for feeding canals.--2. Inland ports: general dispositions. Types of quays, particularly in rivers with great variations of water level. Types of mechanical equipment for loading and unloading vessels. Protection against ice. Rational distributior of winter ports on rivers with intense ice drifts. Sheds and warehouses. Connection with the railway. Establishment and operation costs.--3. Study of hydrotechnical questions by means of laboratory researches on reduced scale models. Comparision of the results of such researches with those of direct observation of the natural phenomena, with a view of ascertaining how far the law of similitude is true.

2d Section: Ocean navigation. Questions: 1. Railway lines and funicular railways giving access to ports; railway installations in ports.--2. Protection of coasts against the sea, with or without preponderating coastal drift of materials.

Communications: 1. Administration of commercial ports. Organisation of the various services of construction, maintenance and exploitation. Results obtained.--2. The use of concrete and reinforced concrete in maritime navigation works. Preservation of such works in salt water.--3. Designs for the working of closing-appliances of dry docks and locks (boat-gates, rolling gates, sliding gates and mitre-gates) Electrical appliances for the automatic working of gates and their accessories.
