Melik was born in the village of Črna Vas in Carniola, part of Austria-Hungary.
Before and during World War I, he studied at the University of Vienna, graduating in 1916 in history and geography.
In 1935–1936, the publishing house Slovenska matica published his monumental work Geografija Slovenije (The Geography of Slovenia) in two volumes with a general regional part, later extended with four additional books between 1954 and 1960, with a detailed regional description of particular areas of Slovenia: the Alps, Styria with Prekmurje and the Meža Valley, the Lower Sava Valley, and the Slovenian Littoral.
His two brothers Franc Melik (born 1885), and Ivan Melik (born 1894) were killed in a grove known as Kosler's Thicket (Slovene: Kozlerjeva gošča, named after its former owner Peter Kosler), on November 25, 1943[1] together with 12 other victims by a unit of the collaborationist Slovenian Home Guard militia under the command of Franc Frakelj.
For his work on the geography of Slovenia and Yugoslavia, Melik received the Prešeren Award in 1947, 1949, and 1951.
